Six patients treated with cloned immune cells experienced partial remission of metastatic melanoma, and one remains in full remission three years later, according to a study published in the Proceedings of the National Academies of Science. Researchers at the Fred Hutchinson Cancer Research Center in Seattle identified and cloned specific cancer-fighting cells in the blood of 11 patients, then infused the cloned cells back into them. An immunotherapy expert, though, said the results were inferior to trials using other methods.
